We need your help with the migration of the data from a very old version of vBulletin to the current one. Our focus is on the data, not on the functionality. We need to migrate all entities, which are possible. Users, posts with attachements, categories, comments, reviews, everything. From one mysql database structure to another. Maybe we need to create a connector/bridge/edi for the data transfer. The tool nedds validation and error handling. Since we are talking about 150000 entities, it is not possible to check manual, if it was working as expected.
